Well, I will agree that you have quite a few medical problems
I'm sure that you understand how difficult it is to know exactly what is going on with you considering the limitations of this forum. For that reason, I cannot diagnose you with any condition. Rather, I can suggest a few possible problems that fit the description you have given and educate you on them. This is in no way a substitute for an evaluation by a health care professional.
Given the symptoms that you have described, I think that rulling out a pheochromocytoma would be reasonable. Pheochoromocytoma is an adrenal tumor that can have the following symptoms:
Headache Diaphoresis (sweating)Palpitations (heart skipping beats)Tremor Nausea Weakness Anxiety, sense of doom Epigastric pain (upper abdomen)Flank pain (sides)Constipation Weight lossAs you can see, there are quite a few of these symptoms that you have. The work-up for this disorder involves urine metanephrines. This is a urine test that looks for breakdown products of catecholamines (adrenalin). I would discuss this workup with your doctor.
Let me know if you need any clarification.
